Frequently asked questions
What is a transposing instrument?
One whose written note differs from the sounding note. When a B♭ trumpet reads C, it sounds a piano B♭.
How do I transpose from concert pitch to B♭?
Choose 'C' as source and 'B♭' as target and type the notes or key: the tool shows everything a whole step higher.
Can I transpose from trumpet to horn?
Yes. Choose B♭ trumpet as source and F horn as target.
